I don`t think the ownership/operation of power armor... is properly described in FO4.
Power armor practically makes you invincible against most melee weapon & bullets..
So wearing Power Armor itself in stranger should be treated as hostile action in my opinion.
(Everyone should flee before confronting anyone in power armor)
For example, Diamond City should never let anyone who is wearing power armor into their city..
because the risk is simply too high to let something so powerful run around.
Also for various vendors...
can you believe these vendors are trying to barter with someone in Power Armor.. who can potentially crush their skull with bare hand and take everything they have?
Not criticizing the game as all games are limited to its own rules and system within the game.
but.. I am wondering what would it be like in more realistic perspective to own a power armor in common wealth.
I think it makes sense for only raider leaders to operate power armor since wearing power armor can tip their power hierarchy instantly.
What would it be like to own a power armor in commonwealth, if you live there?
For me, traveling through common wealth without its protection would be unthinkable.
